Methods for In-Situ Multi-Temperature Measurements Using Downhole Acquisition Tool

A method comprising:

• obtaining a sample of first formation fluid using a downhole acquisition tool positioned in a wellbore in a geological formation;
• stationing the downhole acquisition tool at a first depth in the wellbore, wherein the first depth has an ambient first temperature;
• testing a first fluid property of a first part of the sample of the first formation fluid using the downhole acquisition tool while the downhole acquisition tool is stationed at the first depth to obtain a first measurement point, such that the first part of the sample of the first formation fluid is tested at approximately the first temperature;
• stationing the downhole acquisition tool at a second depth in the wellbore, wherein the second depth has an ambient second temperature different from the first temperature;
• testing the first fluid property of a second part of the sample of the first formation fluid using the downhole acquisition tool while the downhole acquisition tool is stationed at the second depth to obtain a second measurement point, such that the second part of the sample of the first formation fluid is tested at approximately the second temperature;
• and
• determining a temperature-dependent relationship of the first fluid property of the first formation fluid based on the first measurement point and the second measurement point.
